Galileo HAS… even better accuracy

▪Preliminary results from HAS Phase 0 (demonstration phase).

▪ September 2020, 14 stations (only!).

▪ 15-min orbit prediction, 3-day arcs.

▪Main difference wrt standard ODTS:▪Continous clock estimation

▪ IAR for ODTS satellite-station measurements

▪User receiver PPP results promising.

Galileo HAS… moved forward

• OSNMA over-the-air testing since November 2020 without affecting standard OS users. Different OSNMA configurations and processes (key renewal, revocation, etc.) have beensuccessfully tested.

✓ Worldwide dissemination with up to 20 connected satellites and “cross-authentication” concept

✓ No degradation of OS PVT accuracy

✓ Availability of authentic PVT equivalent to standard OS for users with synchronisation requirements better or equal to 30 seconds (works for receiver with time reference up to 5-min error)

• Next steps: OSNMA ICD/guidelines/keys publication and start of “Public Observation Phase”

• Commercial Authentication Service (including signalauthentication) assisted concept consolidated and underprototyping

…stay tuned!

It’s a matter of Trust

World Facing Crises …2021 and beyond

• Global coverage• No ‘mobile’ connection required - Resilience to ground destruction• Uses existing Open Service signal spare capacity• Multi-hazard (tornadoes, earthquakes, nuclear disaster or

industrial disaster, terrorist attacks, …)• On-demand broadcast of an alert message + associated guidance

by Local Civil Protection Authorities• Complementary to existing systems• Reach out population in a timely manner (2-3 minutes), whatever

the size of the area • Geo-location information encoded in the message to target only

the relevant population

• Synergies with Copernicus Emergency Management Service and its other system capabilities

• An interoperable solution studied in cooperation withJapan and India

Example of target area for an

alert message, defined by ellipse.

Ellipse radius is adjustable

The Galileo Emergency Warning Service…

• Remote Activation of Beacons

✓ Under “MRD” formalisation

✓ EUROCAE standard approved

• RCC (or airline) can contact Galileo to remotely activate a beacon via the RLM of Galileo

• Use cases: Aviation: aircraft disappearance, Un-responsive crew; Maritime: overdue vessel

• Two-way (distress) communication

• Enabled by the long Return Link Message; based on predefined Q&A helping the rescue mission

• Distress Position Sharing

• RCC can contact Galileo to share the position of a beacon user in distress with other nearby users
